APPARATUS FOR CARBONATING LIQUIBS.

Patented Dec. 15, 1908.

Applicatibn filed October 20, 1905, Serial No. 283,578. Renewed May 22, 1908. SeralbNo. 434,587.

To all whom it may concern:

Be it known that 1, HENRY PEIN, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have `invented certain new and useful Improvements in Apparatus for Carbonating Liquid, of which the following is a specification.

The object of my invention is'to provide a more simple and efficient means for carbonating liquids than has heretofore been made, and one which requires no other force than the pressure of the gas to operate, thusfpermitting me to produce an apparatus for carbonating and dispensing liquids as is illustrated in my application No. 207869, filed Maj. 13th, 1904, without the cumbersome mechanism ordinarily used for this purpose,

and'which previously has always required an operating force other than the gas pressure.

Further objects of my invention and details of construction will more readily appear from the description hereinafter.

ln the drawings forming part of this specificationligure l'is an elevation of the reservoir of a carbonating machine and the various pipes comiccted therewith. Fig. 2 is a v iew of my improved mixing chamber, wherein the casing` is shown inv section for the purpose of illustrating the incloscd core. Eig.w 3 is an end view of the core, and Fig. 4 is a section taken on the line t-'L of Fig. 2.

My improved mixing chamber is adapted for use in any carbonating machine in`-wliich the li uid and gas may be forced therethroug i, but I will describe it as used in the machine illustrated in the original application referred to herein.

In Fig. '1, l have illustrated an ordinary reservoir 1 for` the storage of sufficient liquid to continuously operate the machine and for the purpose of primarily unitingthe gas and liquid. Leading to the reservoir is a suitable liquid sup ly pipe 2, from which it is fed, and in which ilprovide a valvfl 3 to govern the flow of the liquid therethrough, which may be a valve permitting the liquid to How but one way, so that there will be no back pressure in the pipe 2. This pipe is preferably made to discharge near the top of the reservoir for purposes which will be seen. To the reservoir is also connected a gas tank 4, in which the gas under extreme ressure is stored, and which is connected with the reservoir by means of the pipe 5; which passes to a point near the bottom of the reservoir and is provided with. various valves, and a. gage 6 for the purpose `of controlling and indicating the flow vof gas through the pipe.

For the pur ose of drawing off the liquid and gas from t ie reservoir for use, I employ a pipe 7 which is connected near the bottom of the reservoir and through which the liquid is forced and a pi e S attached near the top of' the reservoir to receive the gas. It will be seen that in this way the water entering the top of the tank and the gas at the bottom, and beingreversely taken off, that it must necessarily receive a primary mixin The pipes 7 and S may be united in a sing e coupling 9, and above which may be attached to the pipe 9l1 a mixing chamber 10. Beyond the mixing chamber the latter has no peculiar relations to any particular machine, and I will therefore not describe its other connections.

The mixing chamber may also be attached to any part of the pipe as may be desired, so long as the gas and liquid are adapted to pass tlieretlnmlgh.- consists of a casing 10 which is cylindrical, preferably larger in diameter than the pipes to which it is connected, and it is provided with reduced ends l2, interiorly threaded, to receive the pipes at each end, or otherwise connected with the receiving and discharge pipes. Within the casing is a'core'11, which is provided with an interrupted outer` surface, on which the liquid passing through the chamber will become disturbed and properly mixed with the gas, and as I have specifically' used it consists of a cylindrical piece having peripheral threads; one being a right-hand thread at 13, and the other a left-hand thread 15, which cross at short intervals, the outer edge of the threads itting snugly against the inner bore of the casing. The threads 13 and 15 are of different pitch, so that the two will not intersect at the same point on the core and thus form a regular channel where the threads run down. One thread may be, say a pi-tch and the other 4 so that the points of crossing will be irregular. l

Vhen the liquid and air enter from the reservoir, whether they be previously mixed or 'lhe mixer or carbonator los not, they pass into an angular slot 14 in the end ges enter seperately or it the ges has been partly united with the liq uid, so that by the time they reach the ends of the threads, the gas and liquids have been so perfectly mixed that it is equal to or better than the mixture caused by various other devices now in general use. lt will be seen that this is not only a very simple ineens for uniting the I face of the coro ol" the mixing chamber, i do not Wish to limit myself to channels being -forined bv the integral threads or the like on the periphery of the core; the seine muy be formed on the interior of the casing with similar results.

After the liquid has passed through the mixing chamber, it has been properly mixed snd is ready for sueh distribution es may he desired.

Sonie of the features of invention may he used independently without departing from the spirit of niyinvention.

Having described my invention, what l claim is 1. In a carbonsting apparatus, the combination of a casing and o core in the casing having eripherol channels rec urrently crossing eacliother.

* 2. In n mixing chamber for uerated liquids, the combination of :t casing, s core within the casing, seid core being provided with intercepting threads on its outer surieee, the edges of which threads contacting with said easing, end inlet and outlet pipes for said threads.

3. In e mixing chamber for sere-ted iiqnids', the combinetion oi e casing, e nere @ossee Within the casing, said core being provided with intercepting threads, und inlet and outlet pipes for said threads.

et. in mixing chamber for eerated liquids, the combination of a easing, o. core within the casing, sind intercepting threads ou seid coro running in reverse directions, und inlet und outlet pipes for seid threads.

in e mixing device for deleted liquids, the combination of easing, u core within the cusing, seid core huving spiral threads running in reverse directions end intercepting each other, the outer extremities of said threads being in Contact with said casing, and inlet und outlet pipes for seid threads.
